Abstract

This thesis describes the synthesis of methylpalladium(II) complexes
bearing various N-heterocyclic carbene (NHC) ligands. The decomposition
behaviour of a subset of these complexes is also studied.
The catalytic performance of methylpalladium(II) complexes bearing
NHC ligands of similar steric bulk but varying basicities was assessed.
Palladium(II) complexes bearing two large NHCs were found to be inactive in the
Heck reaction of 4-bromoacetophenone and n-butyl acrylate, while
methylpalladium(II) carbene dimers bearing bridging halide groups were found to
be active pre-catalysts. Ligand basicity was shown, in some cases, to dramatically
influence catalytic activity. In addition, the catalytic activity of [Pd(NHC)Me(PP)J13F4-type
complexes was assessed. Such complexes were also found to be
inactive.
